Never forget when Jaden Smith and Kylie Jenner left the theatre looking like this.

Never forget when Jaden Smith and Kylie Jenner left the theatre looking like this.

They've been rumoured to be dating, but have continually claimed they are just good friends.

But this might be the first time Jaden Smith and Kylie Jenner have been seen holding hands.

The teenagers looked completely at ease with each other as they left a screening of Brad Pitt's zombie film World War Z.

Jaden, wearing a black hoodie, was seen reaching out his hand and placing it in Kylie's palm.

Kylie dressed casually for the outing in denim shorts, a black T-shirt and trainers.

The two have denied being a couple despite regularly being pictured out as a pair.

They were first seen together when Kylie watched aspiring musician Jaden perform as one of the opening acts for Justin Bieber at his London concert in March.

But after numerous appearances together, Jaden referred to her as his 'friend' in the May issue of Wonderland magazine: 'She's one of my best friends. It's pretty awesome.'

While he has nothing but positive things to say about Kim Kardashian's younger half-sister, his father Will balked at being compared to the highly-publicized family.

'For our family, the entire structure of our life, our home, our business relationships - the entire purpose is for everyone to be able to create in a way that makes them happy,'

the Men In Black actor explained to Vulture writer Claire Hoffman when she asked if the families were similar in regards to Jaden and Kylie's budding relationship.

'Fame is almost an inconsequential by-product of what we’re really trying to accomplish,' explained the Fresh Prince Of Bel-Air star.

'We are trying to put great things into the world, we’re trying to have fun, and we’re trying to become the greatest versions of ourselves in the process of doing things we love.
